we found the air power great for horses that breathe really heavy (asthma etc.) really helps open the airways
the alpha omega respi free we've been using on a horse that seems to get allergy like symptoms runny ,gucky eyes, clear drippy nose etc. and the respi free really clears him up we only use it for about a month then he's good for the summer.
We've also had good luck with zev for a horse with a dry cough and no other symptoms, he cleared right up
Losers say " Why don't they do something? "
Winners say " Here's something I can do. "
